Navy's Mike Greene set an outdoor Heptagonal meet record with a qualifying time of 46.16 in the 400-meter dash in today's opening-round competition of the Heptagonal Outdoor Track and Field Meet at the Naval Academy's Ingram Field.

Eight Ivy league schools and Army and Navy are competing in the two-day event. Sunday's finals begin at 10 a.m.

Entering Sunday's finals, Princeton's men lead with 48 points. Navy (25) followed, with Army and Brown (23) tied for third. Army's women lead with 28 points, followed by Harvard (18) and Dartmouth (12).

Greene's time, which broke the mark of 46.5 set in 1981 by Pennsylvania's Jeff Hill, also qualified Greene for the NCAA championships in Indiana in June.

"For the first 200 meters I was working really hard because that's the way you have got to run it," said Greene, a sophomore. "Then for the final 200, I was just trying to hold on."

Greene's coach, Steve Cooksey, wasn't completely satisfied, though. "Sure I'm pleased," he said, "but I don't think we're finished yet. I would like to see Mike run a 45.5.

"Mike stutter-stumbled out of the starting blocks. He didn't attack the first 200 the way I wanted. I think there is plenty of room for improvement."

Princeton freshman Kent George Jr. won the javelin toss with a throw of 212-9. George was using a "new" javelin that is weighed down heavier in the front.

"That was an excellent throw, considering the new javelin," said Tigers Coach Fred Samara. "Most people are losing 15-20 feet with the new one. Kent seems to be gaining 20 feet."

"I was just able to get low," said George. "Everyone else was throwing with a really high javelin angle of 50-60 degrees. I was getting it at 20-30 degrees and was able to nail it through the point."

Army's Wendell Champion took first in the long jump with a leap of 24-8 1/2. Champion, who fouled two weeks ago at the Penn Relays in Philadelphia on a "mid 25-foot jump," was hoping to break 25 feet today in order to qualify for the NCAA championships.

"The track surface here is new," said Champion, "and that took away some of the spring because it was so soft."

Brown's Gerry Domini won the shot put with a throw of 61-5 1/4. Princeton's Sean Purcell finished second with a toss of 59-8.

Other winners included Cornell's Grant Whitney in the 10,000-meter run (29.17), Yale's Glen Archer in the pole vault (16-0) and Yale's Jim Driscoll in the hammer throw (209-1).

Army's Pamela Pearson won the long jump in 19-6 1/2. Penn's Robyn Forstch took the javelin with a throw of 149-20 and Harvard's Lois Brommer won the 10,000-meter run in 34.36.
